MACHINE FQR'MAKENG BRAID OF VAREABLE WIDTHS.

SPEGIFIGATION forming part of Letters Patent No. 621,099, dated March 14, 1899-.

Application filed May 13, 1898.

To all whom it may concern: i

Be it known that I, J AKOB EMIL KIRBERc,a subject of the Emperor of Germany, (having resided in the United States one year last past and having declared my intention of becoming a citizen thereof,) residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and usefullm- ,provement inMachines for Making Braid of '0 Variable lVidths, which improvement is fully set forth in the following-specification and accompanying drawings. Y

My invention relates to a machine for making braid of variable widths; and it consists I; of an attachment for such machine whereby the tension on the thread or yarn may be varied at intervals, and thus cause the braid to be formed wide and narrow.

Figures land 2 represent side elevations, at a right angle to each other, of an attachment for a braiding-machine embodying my invention, including also portions of such machine necessary to illustrate the operation of said attachment. .Fig. 3 represents a bottom represents a side elevation of another detached portion on an enlarged scale. Fig. 5 represents a plan view of a piece of braid made in accordance with rnyinvention. Figs. 6 and 7 represent a side elevation and a section, respectively, of a portion of a modification.

Similar letters of reference indicate corresponding parts in the figures,

Referring to the drawings, A designates a series of spools which are freely mounted on the spindles B.

O designates tension-weights placed on the spools A, each consisting of two or more members flexibly connected by the cords of chains D, the latter having knots or shoulders E as stops on the under sides of the upper weights, so that when said connections are raised the upper weights are disposed as shown in Figx- 4, thus reducing the tension on the spools The thread or yarn from the spool is guided through the stirrnps F and twisters G, and

thence to the braiding-machine H, which several features in their construction and opera,

tion (excepting the flexibly-connected weights plan of a detached portion thereof. Fig. 4:

Serial No. 680,573. (No model.)

C) are well known in the art and need no special description at this time.

J designates a rising-and-falling head which. is mounted on the standard K at the center thereof and the guides L at the sides thereof, said standards and guides rising from. the feet or base M, which sustain the same, and said head being connected with the weights 0 by the cord or chain N. Bearing against the hub of said head J and the bearing P of the standard K is the spring Q, whose tendency is to quickly depress said head and permit the rapid descent of the weights 0. On said bearings P are the pulleys R, around which are passed the chains or cords S, which are also passed around the pulley T, the latter being mounted on the hanger U, which is suitably connected with the frame or housing of the machine.

The chains S are attached to the crank-arm 7c V, which is mounted on the wrist-pin W of the crank-wheel X, the shaft Y- of the latter being connected with or forming an extension of one of the shafts of the rolls A of the machine, by which the braid is carried away, said rolls being operated by suitable members of said machine.

The wrist-pin or stud Wis connected with the diametrical bar Z, which is freely fitted to the crank-wheel X so as to be capable of adjusting said pin' near .to or farther from the center or axis of said wheel, and thus change the diameter ofthe circle described by the arm V, and consequently vary the degree that the head J and the upper weights C may be lifted in order to adjust the action of said weights on the spool. The head J may also be vertically adjusted in relation to the weights C and wrist-pin W by means of the movable collar 13, which supports it on the standard K. p

As the wheel X rotates the arm V follows the .ot'ary motion thereo and soraises. and lowers the connection S, and with it the head J, whereby the upper weights 0 will likewise 5 be raised and lowered, said weights thus being either removed from thelower weight or superimposed thereon, so as to decrease or increase the tension on the spools, and thus vary I thedl'aft on the thread or yarn, it being no'-' 1 1 4o vented from shifting by means of the studs tieed that the lower weight 0 remains on the spool for. imparting, the established primary tension thereon;

The threadsfrom the spools A constitute the filling, while those from the spools of the ma-- chine II constitute what may be termed the braiding ends of the braid, it being remembered that saidmachine is organized for making braid, as well known but it will here be noticed that as the braiding progresses as the filling-threads are subjected to a greater tension by the descent of the upper or auxiliary movable weights'pn the lower'one, as has been stated, the filling-threads will be drawn apart or spread at the point or place of braiding and so held as the braiding ends are interwoven therewith, producing a wide fabric. When, however, thetension,is released, the filling-threads are permitted to be drawn together by the said ends, and thus the fabric will bemade narrowor\ of normal width. Then at another interval the widening of the fabric is repeated and aga narrowed, and so the operation contin use, i elength of each varying width of fabriclibeing determined by the adjustment of thenvrist-nin of the crankwheel X.

In Figs. 6 and 7 I show the pinion O employed in lieu of the crank-wheelX, thesame receiving motion from the gear-wheel D, the latter being mounted on one of the shaftssay E--locat edin vne present case above the rolls A, the pinion G, however, being mounted loosely on one of the shafts Fof said'rolls,

as in Fig. 2. 0n the pinion is the adjustable diametric bar G, which is provided with the wrist-pin H, on which the arm J is mounted, said arm having the chain or cord K attached to it. The bar G is connected with the pinion C by means of the screw or pin L and pre- M, which project from said pinion and embrace the'opposite sides of said bar, whereby the connection K up and down receives motion similar to the connection S, Fig. 1.

In order to permit the pinion to rotate freely on the shaft F, which latter may be caused to operate by the action of the rollers A, said pinion has freely connected with it the collar N, which latter is secured to the shaft F by means of the screw P, it being noticed that I claim as new, and desire to secure by Letters Patent, is-
